Authorized User: How to Build Credit on a Family Member's Card

Quick answer: an authorized user is someone added to another person’s credit card. You aren’t legally responsible for the debt, and if the issuer reports authorized users, that card’s history can appear on your credit report. It helps only if the card has low balances and on-time payments.

One of the fastest ways to start building U.S. credit is to lean on the good history of someone you trust. You do it by becoming an authorized user on their credit card — a very common approach in families.

What is an authorized user?

It’s a person the cardholder adds to their account. An authorized user:

• can get a card in their name and use it (though using it isn’t required);
• isn’t legally responsible for the debt — the primary cardholder is;
• in many cases, gets that card’s history on their credit report.

How it helps you build credit

If the issuer reports authorized users to the credit bureaus, your report will show that card with:

• its payment history (if it’s always been paid on time, it helps);
• its limit and balance (low utilization helps);
• often, its age.

For someone with no history, it can help them get a score sooner and get approved for their own card.

An example with numbers

Say you have no credit history and your sister adds you to a card she’s had for 8 years, with a $5,000 limit, a typical balance of $300 and no late payments. If the issuer reports authorized users, your report can now show:

Now flip it: if that same card carried a $4,500 balance (90% utilization) or had a recent late payment, it could hurt you instead. That’s why choosing the right card matters more than anything else.

How to choose the right card

The family member’s card should have:

1. Always on-time payments.
2. Low utilization (ideally under 30% of the limit, and under 10% is better). See why it matters.
3. Several years of age, if possible.
4. An issuer that reports authorized users to the bureaus. Ask the bank.

The risks

For you:

• If the cardholder pays late or maxes out the card, it can hurt your report too.

For the cardholder:

• If the authorized user spends and doesn’t pay them back, the debt is the cardholder’s.

Solution: agree on clear rules. Many families decide the authorized user won’t use the card (or won’t even receive it) and just benefits from the history.

What to ask the issuer first

The cardholder can call the number on the back of their card and ask:

1. “Do you report authorized users to all three credit bureaus?”
2. “Is there a minimum age for authorized users?”
3. “What information do you need from the authorized user (SSN, ITIN or neither)?”
4. “Is there a fee to add an authorized user?” (on most cards there isn’t, but some premium cards charge one)

If the answer to the first question is no, adding you won’t help your credit at all.

How to do it, step by step

1. The cardholder logs into their account or calls the bank.
2. They choose “add authorized user.”
3. They provide your name, date of birth and, depending on the bank, your SSN or ITIN (some don’t ask).
4. Check your credit report after a month or two to confirm the account shows up.

If something goes wrong, the cardholder can remove you at any time, and the account usually stops appearing on your report.

It isn’t enough on its own

Being an authorized user is a great start, but lenders also want to see accounts of your own. Pair it with a secured card or a credit-builder loan. See the complete guide to building credit in the U.S..

Beware of “buying” an authorized user spot

Some companies sell authorized user spots on strangers’ cards to boost your score. It’s risky, can be expensive, some scoring models and lenders can detect it, and it doesn’t teach you to manage your own credit. We don’t recommend it.

FAQ

How old do you have to be to be an authorized user? It depends on the issuer: some allow minors, others set a minimum age. Ask first.

Can the cardholder see what I spend? Yes. All purchases appear on the cardholder’s statement.

Can I be an authorized user with an ITIN? In many cases, yes — some issuers don’t even ask for a number. See how to build credit with an ITIN.
